Interestingly, the levels of SRC and PPARB/D expression were highly and significantly correlated in these tumours (Fig 7A), as were the expression levels of PPARB/D andTGFB1 and MMP19, respectively, and to a lesser extent, MMP2, VEGFA, VIM and SNAI1 (Fig 7B, C) (supplementary Fig S14A–D). Here, VIM is linked to neoplasm.
